Specification of Letters Patent.

Patented Feb. 1 1, 1908.4

Application filed August 27. 1907. Serial No. 390.405.

To all whom it may concern:

Be it known that I, DAVID LUMsDEN, citizen of the United States, residing at Cisco, in the county of Piatt and State of Illinois, have invented certain new and useful .Improvements in Olod-Orushers, of which the following is a specification.

The present invention provides a novel implement for pulverizing the soil and which will prevent the machine riding overclods or lumps when drawn over the field, thereby insuring the breaking up of lumps of soil of any appreciable size.

For a full understanding of the invention and the merits thereof and also to acquire a knowledge of the details of construction and the means for effecting the result, reference is to be had to the following description and accompanying drawings.

. While the invention may be adapted to different forms` and conditions by changes in the structure and minor details without departing from the spirit orl essential fea-v tures thereof., still the preferred embodiment is shown in the accompanying drawings, in which:

Figure 1 is a top plan View of a clod crusher embodying the invention. Fig. 2 is avertical central longitudinal section of the implement. Fig. 8 is a front view of the implement. Fig. 4. is a detail perspective view of a side guide. Fig. 5 is a detail perspective view of a draft hitch. Fig. 6 is a detail view of a tooth and a cooperating brace, the dotted lines showing the relation of the parts when slipping the brace upon the teeth and the full lines showing the position of the brace when finally adjusted.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

The implement embodies in its organization, side guides 1 having outwardly eX- tended axle arms 2 upon which are mounted ground wheels 3, each of said guides being provided with a toothed quadrant 4. for coperation with a lock bar 5 for securing a The quadany manner. A lever 6 is pivoted to the guide 1 at 7 and is provided with a hand latch 8 which is connected with the lock bar 5` for withdrawing the same from engagement with the teeth of the quadrant when it 1s required tol adjust the crushing mechanism. The lock bars 5 are spring actuated and are mounted upon their respective levers 6 1n any manner. Standards 9 are slidable in the guides 1 and are provided at their lower'ends with bearings 10 in which a sh aft or rod 11 is mounted. A rod or bar 1'2 connects the upper ends of the standards 9. Links -13 connect the lower ends of the standards 9 with theforward ends of the lever 6. The links 13 may be readily disconnected at their lower ends from the standards 9, and for this purpose hooks 14 at the lower end of said standards 9 are adapted to pass through openings in the lower ends of the links 13.

A casting 1.5 is fitted to each end portion of the shaft or rod 11 and is provided in a side with a depression 16 forming a seat in which the rear end of a bar 17 is secured. The casting 15 consists of a bar having an opening 18 at one end to receive the shaft or rod 11 and having the depression or seat 16 at its opposite end, said bar being provided at the end having the opening 18 with a lug` 19 to which a tooth 2() is secured, since the function of the part 15 is to connect the pole or tongue 21. with the implement, which will be designated hereinafter as the draft hitch.

The pole or tongue 21 is connected at its rear end to a rod or bar 22, and the front ends of the bars 17 are bolted or otherwise secured to opposite sides thereof. The bars 17 constitute hounds and are clipped or otherwise secured a short distance from their rear ends to the rod or bar 22.

The crushing mechanism is mounted upon the rod or shaft 11 and comprises, essentially, two parts, a lifting portionand a rotary crushing portion. The lifting portion of the crushing mechanism consists of teeth, whereas the rotary crushing portion comprises a series of rotary members provided with blades. Each rotary member consists of a hub 23 and blades 24, the latter being secured at their inner ends to the hub and having their outer ends pointed and their forward edges sharpened so as to readily penetrate the clods or lumps of soil. The

ubs 23 are apertured and receive the rod or shaft 11 upon which the rotary members are mounted so as to turn freely. Spacers 25 are slipped upon the rod or shaft 11 between connect the series of teeth 2() with the rod orV bar 22, their upper forward ends being threaded and passed through openings in said rod or bar 22 receiving nuts 27 arranged upon opposite sides of the said rod to admit of adjusting the inclination of the teeth as well as to provide lfor alinement of said teeth. Each brace 26 is provided at its lower rear end with an eye 28 through which a tooth 2O is passed. A projection 29, upon the front edge of each tooth, engages under the eye of the brace and supports the same, When slipping the brace upon the tooth it is arranged so that the eye 28 occupies a position at a right angle to the tooth, as indicated by the dotted lines ii Fig. 6. After the eye 28 clears the projection 29, the upper forward end of the brace 26 is depressed, as indicated by the full lines in Fig. 6, thereby causing the eye 28 to bind the front and rear edges of the tooth and to be held from downward displacement at its rear end by the projection 29.

The teeth 20 and the blades 24 project below a horizontal plane touching the lowest portions of the ground wheels 3 so as to enter the soil. The teeth 2O lift clods o1y lumps, whereas the blades 24 operating be' tween the teeth and in the rotation of the crusher members, break up said clods or The distance to which the teeth and blades may penetrate the soil may be regulated by proper adjustment of the lever 6, as will be readily understood.

Having thus described the invention, what is claimed as new is:

1. In a clod crusher, the combination of a main frame comprising approximately ver- 'tical guides, standards mounted for vertical movement in said guides, means for adjusting the standards vertically and holding the same in an adjusted position, a rod supported by said standards, means carried by the said rod for lifting clods, and rotary crusher members mounted upon said rod and adapted to coperate with the clod lifting means for crushing the clods.

2. In a clod crusher, the combination of a rod 22, a rod l1, supporting means for said rods, a series of teeth mounted upon the rod 1l, braces between said teeth and the rod 22, and rotary crusher members mounted upon the rod l1 and arranged to operate between the said teeth.

8. In combination, side guides, standards movable vertically in said guides, ground wheels supporting the said guides, a rod mounted in the lower ends of said standards, transversely spaced lifting teeth mounted upon the said rod, rotary crusher members mounted upon the rod and arranged to operate between the said lifting teeth, a pole, connecting means between said pole andthe aforementioned rod, a rod 22 having connection with the said pole, and braces between the aforesaid lifting teeth and the rod 22.

In testimony whereof I affix my signature in presence of two witnesses.

DAVID LUMSDEN.
